It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
A routing path selection method provided by the present invention will be described in detail below.
Fig. 1 is a flowchart illustrating a routing path selection method according to an embodiment of the present invention.
In this embodiment, the routing path selection method is applied to a routing path selection system, where the routing path selection system includes at least one user access server and a central server, each user access server serves users in a respective area, a user can access a network through various user terminals (e.g., a mobile phone, a tablet computer, a palm computer, and other user terminal devices) and obtain various applications such as required video, chat, game playing, shopping, and the like from the network, and the user access server in the area where the user is located provides a network access service for the user, collects access request information of different users, and reports the access request information to the central server for analysis processing. The central server is connected with a plurality of user access servers and is responsible for managing the routing path of each user access server, simultaneously summarizing user access request information reported by different user access servers, counting downlink flow data of different target IPs, periodically counting and analyzing the user request information collected in corresponding data collection periods to obtain a path selection table, and issuing the path selection table to each user access server.
In step S1, user request information is collected.
In this embodiment, the user access server is connected to different user terminals in an area, and collects user request information of different users in the area, where the user request information includes a destination IP address and downlink traffic. In this embodiment, the user access server sends each piece of the collected user request information to the central server.
In step S2, the user request information collected in the corresponding data collection period is periodically statistically analyzed to obtain a routing table.
In this embodiment, the step S2 of periodically statistically analyzing the user request information collected in the corresponding data collection period to obtain a routing table specifically includes three sub-steps S21-S23, as shown in fig. 2.
Please refer to fig. 2, which is a flowchart illustrating a detailed sub-step of step S2 shown in fig. 1 according to an embodiment of the present invention.
In step S21, the destination IP addresses in the user request information collected in the corresponding data collection period are periodically classified, and the sum of downlink traffic of the same destination IP address in the data collection period is counted.
In this embodiment, the central server receives the user request information sent by each user access server, and sets a data acquisition period and a statistical analysis period, for example, the data acquisition period is 7 days, and the statistical analysis period is 2 days, so that destination IP addresses in the user request information acquired in 7 days of the corresponding data acquisition period are classified every 2 days, and a sum of downlink traffic of the same destination IP address in the data acquisition period is counted.
In this embodiment, the time length of the statistical analysis period is less than or equal to the time length of the data acquisition period, on one hand, setting a shorter statistical analysis period can ensure real-time update of the statistical analysis result, and on the other hand, setting a longer data acquisition period can ensure the data volume used for statistical analysis, thereby improving the accuracy of the result.
The user access server reports the received user request information to the central server, and the central server statistically analyzes the user request information received in the corresponding data acquisition period according to the set data acquisition period and statistical analysis period, classifies the user request information according to the target IP addresses in the user request information, and counts the sum of downlink flow of the same target IP addresses.
In this embodiment, classifying the destination IP address includes classifying according to a home location and/or an operator of the destination IP address.
In step S22, a next hop route is assigned according to the classification of the destination IP address and the sum of the downstream traffic.
In this embodiment, the step S22 of allocating the next hop route according to the classification of the destination IP address and the total downlink traffic includes:
according to the classification of the target IP address, acquiring the bearing broadband capacity of the next hop route belonging to the same classification; and selecting the next hop route according to the downlink flow sum and the bearing broadband capacity of the next hop route.
In this embodiment, the central server performs attribute classification such as area and operator on different destination IPs, and each classified area and/or operator corresponds to multiple routing paths, i.e. multiple next-hop routes, and each routing path has its own bearer bandwidth capability, which is different from each other, and selects, according to the statistical downlink traffic of each destination IP in the classification, the next-hop route having a bearer bandwidth capability greater than the downlink traffic as the next-hop route corresponding to the destination IP address.
For example, based on the classification of the region and the operator, the central server divides the IP addresses IP1 and IP2 belonging to the sichuan telecom into the same class, respectively counts that the total downlink traffic of the IP1 and the total downlink traffic of the IP2 in the acquisition period are 50M and 100M, and the routing path from the user access server to the content server (i.e., the resource server corresponding to the destination IP) includes a plurality of paths, selects the routing path belonging to the sichuan telecom, and obtains the bearer bandwidth capability of each path, selects the routing path having the bearer bandwidth capability not less than 50M for the IP1, selects the routing path having the bearer bandwidth capability not less than 100M for the IP2, and records the next-hop routing of the routing paths IP1 and IP2, respectively.
In step S23, a mapping relationship between the destination IP address and the next hop route allocated is recorded, and the routing table is generated.
In this embodiment, the central server generates a routing table according to the mapping relationship between the recorded destination IP address and the allocated next hop route, and issues the routing table to each user access server in communication connection therewith.
In this embodiment, the central server generates a corresponding routing table in each statistical analysis period, and sends the routing table to each user access server, and each user access server directly replaces an old form after receiving a new routing table and uses the new routing table, that is, the newly received routing table is used for routing the routing path of the user request received before the routing table is obtained next time.
And S3, selecting a routing path for the new user request according to the path selection table.
And after receiving the user request, the user access server distributes a next hop route for the user request according to the path selection table. It should be noted that, when the user access server cannot find the destination IP address record in the path selection table, the next-hop routing is selected according to the default routing rule. The user access server reports all the user request information received by the user access server to the central server.
The routing path selection method provided by the invention periodically collects the downlink traffic characteristics of each destination IP address, sets different paths for different destination IPs to travel through the downlink traffic characteristics, can provide services with different types of quality according to the actual traffic request of each destination IP, and can ensure the stability of key services particularly under the condition of insufficient resources.
